Before starting to learn programming, it is very important to master the basics of computer knowledge. Today, I will share some fundamental computer knowledge and concepts, hoping to help everyone~1. Concept of ComputerA computer, formally known as an electronic computer and commonly referred to as a PC, is a modern intelligent electronic device capable of automatically and rapidly processing vast amounts of data according to programs. It consists of hardware and software.2. Classification of ComputersCommon forms include: desktop computers, laptop computers, mainframe computers, etc.Hardware refers to the various physical devices composed of electronic, mechanical, and optoelectronic components within a computer. These physical devices form a whole according to the requirements of system architecture, providing the material basis for the operation of computer software.The five main components of computer hardware are: the arithmetic logic unit, control unit, memory, input devices, and output devices. The arithmetic logic unit and control unit are the core of the computer, collectively known as the Central Processing Unit (CPU); the memory is used to store data, such as RAM and hard drives; input and output devices are used to display information and operate the computer. Common input devices include the mouse and keyboard; common output devices include monitors and printers.Software is a collection of computer data and instructions organized in a specific order. Computer software is essential during the use of a computer; in simple terms, it is what makes a computer perform specific functions according to predefined instructions. Computer software is divided into system software and application software based on its functionality.3. Computer LanguagesComputer language is a special language used for communication between humans and computers. Information can be transmitted to the computer through computer languages. Classification of computer languages includes: machine language, assembly language, and high-level languages.Machine Language: This is a computer language represented directly by binary code instructions, consisting of 0s and 1s. The instructions have a certain number of bits and are divided into several segments, with each segment’s encoding representing different meanings. Reading and writing are cumbersome, making it very unfavorable for development work.Assembly Language: This uses special symbols to replace the binary codes of machine language, which cannot be directly recognized by the computer and requires software to translate assembly language into machine language. Compared to machine language, readability is greatly improved, but the amount of code remains very large.High-Level Language: Programs developed using ordinary English. The completed content is called source code, which is translated into machine language that the computer can directly recognize by a compiler, and then executed by the computer. There are many common high-level languages, such as C, C++, Java, etc.Software Development: The process of creating software using development tools and computer languages.4. Function Keys on the ComputerTab: Tab key, used for indentation.Shift: Shift key.Ctrl: Control key, used in combination with other keys.Alt: Alternate key, used alone to call the window menu, generally used in combination with other keys.Space: Space key, inputs a blank character, i.e., a space.Enter: Enter key, used for line breaks.Windows: Calls up the system menu.5.
